| 1 | +# v1.2.0 |
| 2 | + |
| 3 | +June 2025 |
| 4 | + |
| 5 | +## Highlights |
| 6 | + |
| 7 | +- `aeon` v1.2.0 drops support for Python 3.9, Python 3.10-3.13 are the current supported versions. |
| 8 | +- Framework for whole-series anomaly detection has been implemented, and the module has been refactored |
| 9 | +into `anomaly_detection.collection` and `anomaly_detection.series` submodules. |
| 10 | +- `ProximityForect` and `ProximityTree` classifiers have been improved to support |
| 11 | +unequal length and multivariate series. The classifiers are also significantly faster. |
| 12 | +- The forecasting module has been enhanced with additional methods for direct and recursive forecasting, |
| 13 | +as well as new algorithms such as ETS. This module is still in early development, and we expect |
| 14 | +framework changes in future releases. |
| 15 | +- The similarity search module has been significantly reworked to fit the `aeon` style |
| 16 | +framework seen in other modules. See the module examples and documentation for more details. |
| 17 | +- The start of a sub-package for self suprervised learning has been added in |
| 18 | +`aeon.transformations.collection.self_supervised`, starting with the `TRILITE` algorithm. |
